What You'll Learn

Use a flat tool for gentle leverage
One of the easiest ways to separate plastic storage bins is by using a flat, sturdy tool like a butter knife, putty knife, or spatula. Here is a step-by-step guide on how to do it:
Firstly, gently insert the tool between the two bins where they are stuck. Then, wiggle the tool slightly to create a small gap. Slowly work your way around the edges, applying even pressure to avoid cracking the plastic. It is important to avoid using sharp tools like screwdrivers, as they can scratch or damage the bins.
Once you have created a gap, gently pull the bins apart. If the bins are still difficult to separate, you can try applying a small amount of lubrication. Use a thin layer of dish soap, cooking oil, or silicone spray to the edges where the bins are stuck. Let the lubricant sit for a few minutes to penetrate the seal, then gently twist and pull the bins apart. Remember to wipe off any excess lubricant after separating the bins to prevent slipping or staining.
Another method to consider is to apply heat to loosen the plastic. If the bins are stuck due to tight stacking or temperature changes, a hairdryer on a low or medium setting can help expand the plastic slightly, making it easier to separate them. Move the hairdryer evenly around the edges for a few minutes. However, it is important to avoid using high heat or direct flames, as this can warp or melt the plastic.
Additionally, you can try the "air nozzle trick". If there is an air gap between the bins, blowing air into the gap can help to create a slight pressure difference, making the bins easier to separate. Alternatively, filling the inside bin with ice water and dunking the outside in hot water can also create a temperature difference that may loosen the seal.

Apply heat to loosen the plastic
If your plastic bins are stuck together due to tight stacking or temperature changes, applying heat can help expand the plastic, making it easier to separate them. Here are some detailed steps to help you loosen the plastic and free your bins:
Firstly, grab a hairdryer and set it to a low or medium setting. You don't want to use high heat or direct flames on the plastic, as this could warp or melt it. Hold the hairdryer a few inches away from the bins and focus on the edges where they are stuck. Move the hairdryer evenly around these edges for a few minutes.
If you don't have a hairdryer, you could try filling the inner bin with ice water and then dunking the outer bin into a tub of hot water. The hot water will heat and expand the plastic, while the cold water will contract the inner bin, making it easier to separate the two.
If you're worried about using water, you could try warming the outer bin with a heat gun or hot air gun. These tools can get very hot, so be careful not to overheat the plastic. Work slowly and keep the heat gun moving to avoid concentrating the heat in one area.
Once the plastic has expanded due to the heat, you can try other methods to separate the bins. For example, you could use a flat tool like a butter knife or spatula to gently work your way between the bins, prying them apart. Or, you could try using lubrication—apply a thin layer of dish soap, cooking oil, or silicone spray to the edges, wait a few minutes, and then twist and pull the bins apart.
With these methods, you should be able to safely loosen the plastic and separate your bins without causing any damage.

Use lubrication for stubborn bins
If your plastic bins are stuck together due to moisture or friction, lubrication can help. First, try to twist and wiggle the bins to break the seal. Hold the bottom bin firmly and grip the top bin, twisting it gently from side to side while pulling upward.
If this doesn't work, apply lubrication. You can use a small amount of dish soap, cooking oil, or silicone spray on the edges where the bins are stuck. Let the lubricant sit for a few minutes to penetrate the seal. Then, gently twist and pull the bins apart. Remember to wipe off any excess lubricant afterward to prevent slipping or staining.
You can also try using a flat tool for gentle leverage. Insert a flat, sturdy tool like a butter knife, putty knife, or spatula gently between the two bins. Wiggle the tool slightly to create a small gap, and slowly work your way around the edges, being careful not to apply too much pressure and crack the plastic.
Another option is to apply heat to loosen the plastic. Use a hairdryer on a low or medium setting to warm the edges of the bins. Move the hairdryer evenly around the edges for a few minutes. You can also try the hot and cold water method by filling the inside bin with ice water and dunking the outside in hot water. However, avoid using high heat or direct flames, as this can warp or melt the plastic.

Tap edges with a rubber mallet
If your plastic bins are stuck together, one way to separate them is by tapping their edges with a rubber mallet. This method is particularly useful if the bins are tightly wedged together, as tapping the edges can help loosen them.
To do this, place the bins on a flat surface and use a rubber mallet to gently tap the edges of the bins where they are stuck together. Start by tapping the mallet gently against the edges of the bins, being careful not to use too much force, as this may cause the plastic to crack or break.
As you tap, you may need to apply slight upward pressure to help loosen the bins. Continue tapping and working your way around the edges, paying close attention to the areas that seem most stuck. The gentle impact of the rubber mallet helps to create a slight separation between the bins, breaking the seal that is holding them together.
If the bins are still not separating, you can combine this method with other techniques, such as twisting and wiggling the bins or using lubrication. Try holding the bottom bin firmly in place while gripping and gently twisting the top bin from side to side, applying slight upward pressure. You can also try applying a thin layer of dish soap, cooking oil, or silicone spray to the edges of the bins before tapping with the rubber mallet.
Remember to work slowly and gently to avoid damaging the plastic bins. With patience and persistence, you should be able to separate the stuck-together plastic bins using the rubber mallet technique.

Use liners or dividers
Plastic storage bins are a versatile and practical solution for organising your home, garage, or workspace. However, these bins can sometimes become stuck together due to pressure, humidity, or friction, making them difficult to separate. One way to prevent this issue is to use liners or dividers.
Liners or dividers can help reduce friction between the bins, making them easier to separate if they become stuck. Here are some tips for using liners or dividers effectively:
- Choose the right material: Use a sheet of parchment paper, wax paper, or a thin plastic liner between the bins. These materials provide a smooth surface and reduce friction.
- Cut the liner to size: Ensure the liner is large enough to cover the entire surface area where the bins touch. You may need to cut the liner to fit the specific dimensions of your bins.
- Place the liner properly: When stacking the bins, carefully place the liner between them. Ensure the liner stays in place as you stack, avoiding any bunching or folding that could create additional friction.
- Use dividers for larger spaces: If you have larger bins with significant space between them, you can use pool noodles or similar items as dividers. Cut the pool noodles into sections and place them between the bins to prevent direct contact and reduce friction.
- Combine with other prevention methods: Using liners or dividers is an effective strategy, but you can also combine it with other preventive measures. For example, avoid overloading the bins with heavy items, store them in a dry area to prevent moisture buildup, and choose bins with handles for easier grip and separation.
By following these tips, you can effectively use liners or dividers to prevent your plastic bins from becoming stuck together. This method offers a simple and practical solution, ensuring that you can separate the bins without causing any damage. Remember to consider the specific characteristics of your bins and the storage environment to tailor your approach accordingly.
